Arrangement for washing transparent parts of vehicles

Abstract

Arrangement for washing transparent parts of vehicles, particularly windshields and lightlamp lens shields of motor vehicles. The arrangement includes a solid liquid conducting member and a bore-like liquid supplying channel extending therethrough between an inlet port and an outlet port. A liquid conduit communicating with a liquid container has a terminal portion distant from the container and provided with a connecting piece press-fit or with prestress inserted in the inlet port. A nozzle body is associated with the outlet port and has a discharge aperture aimed at the transparent part to be washed. A selectively actuable liquid releasing means is operable to release liquid to travel from the container under pressure at the driver's command to the nozzle body.

What we claim is: 
     
       1. In a vehicle, an arrangement for washing lens shields of vehicle lamps, comprising a bumper having a bumper guard, said guard having a portin of solid cross-section; supply means for washing liquid; a spray nozzle means mounted on said bumper guard of the vehicle so as to face towards the lens shield; a channel passage extending through said solid portion of the bumper guard and connecting said liquid supply means with said nozzle means; and means for propelling said liquid towards said nozzle means. 
     
     
       2. An arrangement as defined in claim 1, wherein said channel passage has an inlet port at one end thereof and an outlet port at the other end thereof. 
     
     
       3. An arrangement as defined in claim 2, wherein said spray nozzle means is associated with said outlet port. 
     
     
       4. An arrangement as defined in claim 3, wherein both said inlet port and said outlet port have a diameter larger than that of the remainder of said channel passage. 
     
     
       5. An arrangement as defined in claim 3, wherein said nozzle means is a nozzle body press-fit inserted in said outlet port. 
     
     
       6. An arrangement as defined in claim 3, wherein said nozzle body is inserted into said outlet port with prestress. 
     
     
       7. An arrangement as defined in claim 4, wherein said liquid supply means includes a liquid conduit having a terminal portion provided with a connecting piece engaged in said inlet port. 
     
     
       8. An arrangement as defined in claim 7, wherein said solid bumper guard portion is made of an elastic material yielding to pressure, so that said nozzle means and said connecting piece may be inserted into, respectively, said outlet port and said inlet port elastically enlarged. 
     
     
       9. An arrangement as defined in claim 7, wherein said connecting piece is provided with at least one peripheral annulus having a wall sloping in the direction of insertion of said connecting piece into said inlet port and having, opposite to said sloping wall, a radially positioned rear wall obstructing falling out and extraction of said connecting piece from said inlet port. 
     
     
       10. An arrangement as defined in claim 7, wherein said nozzle body is provided with at least one peripheral annulus having a wall sloping in the direction of insertion of said nozzle body into said outlet port and having, opposite to said sloping wall, a radially positioned rear wall obstructing falling out and extraction of said nozzle body from said outlet port. 
     
     
       11. An arrangement as defined in claim 4, wherein said nozzle body is fixed to a carrier inserted in said outlet port with prestress. 
     
     
       12. An arrangement as defined in claim 4, wherein both said nozzle body and said connecting piece are made of an elastic material. 
     
     
       13. An arrangement as defined in claim 1, wherein said supply means for washing liquid includes a container and a liquid conduit communicating with said container and having a terminal portion distant from said container and provided with a connecting piece engaged in said inlet port. 
     
     
       14. An arrangement as defined in claim 13, wherein said container stores the washing liquid in pressurized condition and said liquid releasing means is provided on said nozzle body and is connected to means actuable by the driver to cause release of the washing liquid. 
     
     
       15. An arrangement as defined in claim 13, wherein said container has associated thereto a selectively operable pump and said releasing means includes a switch connected to said pump and actuable to start and stop the operation of said pump. 
     
     
       16. An arrangement as defined in claim 13, wherein means is provided for attachment of said solid bumper guard portion to the vehicle bumper. 
     
     
       17. An arrangement as defined in claim 16, wherein said attachment means includes a threaded bolt firmly anchored in said bumper guard and projecting from said solid portion of said guard by a threaded portion thereof screwable into a female threading provided in the bumper whereto the guard is to be fixed. 
     
     
       18. An arrangement as defined in claim 17, wherein said attachment means includes a notch provided on the rear side of said solid portion of the bumper guard which notch has a form conformed to the cross-section of said bumper, so that when said solid portion is engaged on said notch with the bumper a stable alignment of the solid portion of said bumper is achieved.
